View Full Version : Question about Sand

10/03/2017, 12:02 PM
I have a 90Gal tank that has been running since early this year, we had upgraded from a 30 gal and used all new sand but it's the CaribSea ocean direct original and there are lots of larger particles that have settled to the top and have accumulated corralline algae and other algae making the sand bed look brown and gross.

I'd like to either sift out the larger particles or remove and replace the sand with a smaller particle size what do you suggest I do? sift? or replace?

Vacuum off the gross layer over time with water changes, add more new sand if you start to get bare areas. Make these changes slowly over time instead of all at once.

Consider some sand stirring livestock - a cucumber, conch, goby, etc. And keep nutrients in check to prevent more ugly growth.
